水箱水位控制器的设计与实现

介绍了水箱水位控制中一种新型的实用电路。它是采用数字电路与模拟电路相结合、集成电路与分立元件相结合的方法，通过红外光电传感器将水箱水位的高低信号转换成开关数字信号，然后在控制电路和驱动电路的作用下实现对水箱水位的自动控制和故障报警。该电路具有简单、经济、稳定可靠、容易实现的特点，适用于城镇居民楼房，特别是农村住宅楼房生活用水水箱的水位自动控制。

Design and Realization of the Water Level Controller of the Water Tank

A novel practical circuit to control the level of the water tank is presented. It is a combination of digital circuit and analog circuit composed of integral circuits and separate components. Through infrared photoelectric sensor, the water level is converted into digital switching signal, then automatic level control and failure alarm are accomplished by control circuits and drive circuits. The circuit features simple, economical, stable and reliable, It is suitable for application of water level automatic control in resident buildings, especially in rural areas.
